Dimensions and loading of a truss beam are given in the figure.
a) Calculate all the member forces of the truss by using the method of joints and list them in a table.
b) Calculate the member forces of S2, S, and So by using the RITTER method of sections.
c) Check the safety of the members S and S by using allowable stress Oa.
